Answer:
Plates may converge directly or at an angle. Three types of convergent boundaries are recognized: continent‐continent, ocean‐continent, and ocean‐ocean. Continent‐continent convergence results when two continents collide. The continents were separated at one time by oceanic crust that was progressively subducted under one of the continents. Ocean‐continent convergence occurs when oceanic crust is subducted under continental crust. This forms an active continental margin between the subduction zone and the edge of the continent. Ocean‐ocean convergence occurs when two plates carrying ocean crust meet. One edge of ocean crust is subducted beneath the other at an ocean trench.
